Zillergrund Reservoir Tunnel - Schwaz, Tyrol, Austria; "The Austrians do like their tunnels. The road up from the Zillertal Valley finishes at the top of the Zillergrund Dam at a height of 6,070 feet above sea level. Then there is an excellent walk up to the Plauener Mountain Hut. The walk starts with a nice flat tunnel. Then it's up, up and a bit more up, to the Hut at 7756 feet." - by Dave Hanmer, via Flickr
